QTestLog: Properly own the loggers

Previously, the loggers would leak if the application failed to call
stopLogging(). Now they are owned by the global static which will delete
them in that case.

Also, since we have to adapt loggerCount() to the fact that std::vector
uses size_t, recognize that we only ever want to know whether the number
of loggers is 0. Change the method to only provide that information
rather than the actual number.
